Cost of change change

Business requirement

2x

Development

3x

Operation

4x

Infrastructure

Integration costs

  • Integration is Hard!

  • Different system vintages

  • Mainframe, EAI Hub, MOM, EJB, Web Services

  • Systems must collaborate

esb

Integration costs

  • Protocol (IIOP, DCOM, JMS, MQTT, AMDP, …)

  • Standard (JBI, EJB)

  • Data Format (XSD, JSon)

  • Data Mapping (csv to XML)

Continuous Delivery Strategy !

“WTF is DevOps?”

  • IT is a core competency

  • Set of principles

  • There’s more to applications than coding!

  • Feedback, Repetition

  • Communication

  • People!

wtf-dev-ops

“Coder, programmer”

developer

“Interest”

languages

java, web2, html, js, unit test, …

“Operation guy”

opts it

log, cpu, thread blocked, report, procedure, alert, monitoring, …

Strategy

  • Objective Continuous Integration strategy

  • Establish a concrete pipeline to production

  • Build/Test/Release more often

idea

Impact

  • Bottlenecks ?

  • Involves Dev & Ops to be successful

  • Every build "release candidate"

collaborate

Automate Pipeline

  • Developer

    • Unit test

    • Integration test

    • Build

    • Deployment

    • Doc / Release

devops2

Automate Pipeline

  • Operations

    • Setup (V)Machine

    • Provisioning software

    • Deploy procedures in QA/UAT/PROD

Platform

  • Machine → VM

  • VM → Linux Container

  • Red Hat Atomic Enterprise Platform

Process

docker-animated-1

Docker

docker filesystems multilayer

  • Union FS mounted with immutable images

  • Benefits: portability, reusability, versioning, application-centric

Docker config

dockerfile

Docker

  • Container runtime, image distribution, Process launcher

Management platform

softshake-2015

Kubernetes

  • Runtime & Operational management of containers

  • ApiServer (event, status), Scheduler, Controller & State Storage

  • Agent - Kubelet - manage containers on host

  • Containers pods (= shared docker containers)

Kubernetes

kubernetes-platform

Pod & docker

fabric8 pod

  • Communicate to each other using skyDNS to resolve hostname

Pod & port

fabric8 pod port

  • Ports can be exposed

Pod & volume

fabric8 pod volume

  • Share data using mounted volume between host & container

Kubernetes Service

fabric8 service pod

  • Kube Service loadbalanced through the pods using HA-Proxy Routes map private with public IP address

Kube Application JSon

kubernetes-json-1

kubernetes-json-2

 

Platform as Service

softshake-2015

OpenShift v3

  • Designed around Kubernetes, Docker, Fabric8

  • Provide new features

    • Docker Images Registry & Certification

    • SSO - Authentication Server

    • Api for Management, Client Command Line

    • Build S2I
